onClick在執行AsyncTask時崩潰的應用程序

我遇到了一些AsyncTask問題，我嘗試使用按鈕onClick事件來運行。我曾在「HomePageActivity」中工作，但隨後將代碼轉移到新的活動中，現在該應用程序在單擊該按鈕時崩潰。它曾經完美地工作。onClick在執行AsyncTask時崩潰的應用程序

任何人都可以幫我解決這個問題嗎？我相信這是一個新的眼睛可以發現的簡單。

public class GamesOverview extends HomePageActivity { 

public final static String BaseUrl="http://URL.com/"; 
ArrayList<DEPT_HOLD> deptList=new ArrayList<DEPT_HOLD>(); 

private class GetDeptAyncTask extends AsyncTask<Hashtable<String,String>,Void,String>{ 
// Parse in background 
@Override 
protected String doInBackground(Hashtable<String,String>... params) { 
    @SuppressWarnings("rawtypes") 
    Hashtable ht=params[0]; 
    @SuppressWarnings("unchecked") 
    String json=HelperHttp.getJSONResponseFromURL(BaseUrl+"JSONURLGOESHERE", ht); 
    if(json!=null) parseJsonString(deptList,json); 
    else { 
    return "Invalid Company Id"; 
    } 
    return "SUCCESS"; 
} 
// Parse JSON 
protected void parseJsonString(ArrayList<DEPT_HOLD> deptList,String json) { 
    try { 
    JSONObject top = new JSONObject(json); 
    JSONObject topAdds = (JSONObject) top.get("topAdds"); 
    JSONArray array = (JSONArray) topAdds.get("player"); 
    for(int i = 0; i < array.length(); i++) { 
    JSONObject j = array.getJSONObject(i); 
    DEPT_HOLD d = new DEPT_HOLD(); 
     d.one = j.optString("percent",""); 
     d.two = j.optString("id",""); 
     deptList.add(d); 
    } 
    } catch (JSONException e) { 
    e.printStackTrace(); 
    } 
} 
// Execute post 
@Override 
protected void onPostExecute(String result) { 
    if(result=="SUCCESS") { 
    Toast.makeText(GamesOverview.this, "Success"+deptList, Toast.LENGTH_SHORT).show(); 
    DeptArrayAdapter adapter=new DeptArrayAdapter(GamesOverview.this,R.id.text1,deptList); 
    ListView listv=(ListView)findViewById(R.id.lv); 
    listv.setAdapter(adapter); 
    } 
    else{} 
}  
} 

public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 

    // Scrolling 
    ScrollView scroll; 
    scroll = new ScrollView(this); 
    HorizontalScrollView horizontalscroll; 
    horizontalscroll = new HorizontalScrollView(this); 
    // End 

    // Get JSON button 
    final Button JSONButton = new Button(this); 
    JSONButton.setText("Get JSON"); 
    JSONButton.setTextSize(20); 
    JSONButton.setTextColor(Color.rgb(000,000,000)); 
     JSONButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
     executeAsyncTask(); 
     } 
     }); 
    // End 

    // LAYOUT 
    LinearLayout layout = new LinearLayout(this); 
    layout.setOrientation(LinearLayout.VERTICAL); 
    layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 
    LinearLayout.LayoutParams layoutparams = new LinearLayout.LayoutParams(getWindowManager().getDefaultDisplay().getWidth(),getWindowManager().getDefaultDisplay().getHeight()); 
     layout.setGravity(Gravity.CENTER_HORIZONTAL); 
     layout.setBackgroundResource(R.drawable.body_bg);

      displayJSONButtonlayout_params.setMargins(0,10,0,0); 
      displayJSONButtonlayout.setGravity(Gravity.CENTER_HORIZONTAL); 
      displayJSONButtonlayout.addView(JSONButton,displayJSONButtonlayout_params); 
    // END LAYOUT  

    layout.addView(displayJSONButtonlayout); 
     layout.requestLayout(); 

     // Enable scrolling 
     scroll.addView(layout,layoutparams); 
     horizontalscroll.addView(scroll); 

     // Set content view 
     setContentView(horizontalscroll); 

} 

// Finish up task 
@SuppressWarnings("unchecked") 
private void executeAsyncTask(){ 
Hashtable<String,String> ht=new Hashtable<String,String>(); 
GetDeptAyncTask async=new GetDeptAyncTask(); 
    ht.put("", ""); 
    @SuppressWarnings("rawtypes") 
    Hashtable[] ht_array={ht}; 
    async.execute(ht_array); 
} 

}

所有的logcat的信息，我可以找到

什麼是logcat不得不說的呢？ – codeMagic

你確定你的按鈕顯示..因爲你已經動態地創建了一個按鈕，並且你沒有將它添加到任何視圖，並且你甚至沒有把它作爲你的contentView保留下來 – Pragnani

Logcat似乎並沒有在我正在使用的程序。這是我看的第一個地方，但沒有出現這個崩潰。 – localhost

我解決了這個問題。該應用程序崩潰了，因爲我編寫了使用main.xml佈局顯示的代碼，但一直試圖使用第二個接口來控制main.xml接口。這導致了幫手活動的複雜化。

感謝大家試圖幫助我解決這個問題。

根據您的logcat其完美直到onpostexecute（），我認爲你正在等待獲取從下面的網址一些成果這會導致延遲並完成您的活動。

這也是我的想法。你有什麼建議進行修復？ – localhost

調試代碼與url相關聯，並且符合它的工作原理 –
